Organ ifølge krav 1,kendetegnet ved, at det består af en laminat med et første og et andet lag af kompositmateriale. 3. Organ ifølge krav 2,kendetegnet ved, at det første lag består af glasfiberarmeret epoxy, hvor fibrene forløber i organets tværretning, og at det andet lag består af aramidfiberforstærket epoxy, hvor fibrene forløber i organets længderetning. 4. Organ ifølge krav 1,kendetegnet ved, at laminatet udgøres af et bimetal. 5. Organ ifølge et af kravene 1-4, kendetegnet ved, at det er en flap (4), der er indrettet til fastgørelse nær bagkanten af vindmøllevingen (10). 6. Flap (4) ifølge krav 5,kendetegnet ved, at den har en længde, der svarer til mellem 5% og 70% af vingens (10) længde. 7. Flap (4) ifølge krav 5 eller 6, kendetegnet ved, at den har en bredde, der svarer til mellem 1% og 70%, fortrinsvis 5%, af vingens (10) korde. 8. Flap (4) ifølge et af kravene 5-7, kendetegnet ved, at den omfatter flere langs flappens (4) for- og bagkant sammenføjede og modsat vendende laminater. 9. Flap (4) ifølge et af kravene 5-8,kendetegnet ved, at den er monteret på vingens (10) trykside (2). 10. Vindmøllevinge (10) med et eller flere organer (4) ifølge et af kravene 2-9. 11. Vindmøllevinge (10), der er udformet ud i et med et eller flere organer (4) ifølge et af kravene 2-9.
